ELECTIRlCALLY-HEATED VULANIZER..

naoaaaa.

To all whom t may concern:

Be it known that ll, EDWARD E. Rose, a citizen of the United States, and a resident of Swissvale, in the county of Allegheny and have invented a new and useful improvement in Electrically- Heated Vulcanizers, of which the following `is a specification.

My invention relates to electrically heated io vulcanizers for repairing tires of bicycle and automobile wheels and similar purposes, and it has for its object to provide a device of the above-indicated character that shall embody simple and inexpensive means for effectively attaching the device to a tire in such manner that repairs may be easily made without removing the tire from the wheel.

lln the prior art, provisions have been made for securing similar devices in posi- 2o tion, but usually metallic chains or bent rods have been employed for encircling the rim of the-su.pporting wheel and such chains or rods have been adjustably secured to the body of the vulcanizer by means of coper# ating threaded members and wing-nuts or other similar devices.

Considerable inconvenience and diculty has been experienced with attaching devices ofthe kind referred to, for the reason that the parts thereof became heated during the operation of the vulcanizer and weretherefore diiicult to manipulate and often burned the hands of the operator and scratched or burned the finish of the wheel rims. Furthermore, such devices were cumbersome and inconvenient for a single person to handle.

According to my present invention, l provide simple and adequate means for securing or strapping a vulcanizer in position which t@ overcomes the difficulties hereinbefore mentionedv and generally improves the construction of such devices and increases their utility and Vedectiveness.

ln the accompanying drawings, Figure l t5 is a view in side elevation of a tire and supporting'. wheel to which a vulcanizer embodyn ing my invention is attached. Fig. 2 is an end view of the apparatus shown in lFig. l. lFigl 3 is an enlarged sectional view of the same apparatus, and Figs. 4 and 5 are enlarged detail views of a belt employed inA connection with my invention. v

Referring to the drawings, an electrically heatedgihvulcanizer l is held in position against a tire 2, which is mounted in the dpeeilcaton of Letters Patent.

tion that is electrically heated in a manner that is familiar to those skilled in the art. Secured to the working member 7 is a handle 8 through which a Hexible service cord 9 extends from an inclosed heater unit (not shown) and is adapted for connection toa suitable source of energy (not shown). A plurality of longitudinally disposed cylindrical strain or guide members l() are rigidly and suitably attached to the respective sides of the working member 7 in pairs and are adapted to coperate with the straps or belts 5 and 6 in pairs.

Although l have shown the strain or guide members l0 as rigidly secured to the working member 7 by means of metallic straps, angle irons and channel members, it will, of course, be understood that said strain or guide members may be secured in position in' any other suitable way. -Furthermore, said strain members need not necessarily be associated in pairs, as hereinbefore set forth, as a single strain member may be provided at each side of the working member 7 to cotit dit

operate with the belts 5 and 6, as will be readily understood. o

rThe belts 5 and 6 are preferably made of soft, pliable material, such as leather or webbing, and it is, therefore, evident that injury to the wheel rim 3 is avoided, While none of the parts to be manipulated can be heated.

A plurality of buclrlm 14 are preferably attached lto the middle portion l5 of each belt or strap by stitching, as indicated in dotted lines in Figs. 4 and 5,- although, if desired, other means of attachment may be employed. 'lh-e buckles 14 may be of any well known construction, although l favor a buckle of the familiar self-tightening type, and said buckles are adapted to secure the respective ends of the belts 5 and 6 whereby the v ulcanizer 1 may be tightly strapped in position.

When the vulcanizer l is not in use, one end of each of the belts 5 and 6 is released from its buckle and its strain or guide member, although the other end thereof is se cured to the device, so that all of the parts lli) , of the device are I tire 2 and Wheel 4 hand, after v`-which kept together and loss thereof is prevente In order to attach the vulcanizer tothe for purposes of repair, the Working member 7 may be held in the desired position by one hand, While the free end of each of the belts 5 and 6 is passed around the Wheel rim 3threaded over the proper strain or guide member 10 and through the proper buckle 14 with the other the belts may be tightened to the required degree in order to secure the vulcanizer 1 firmly in position. It Will be found that a single person can' conveniently manipulate"this device in a very short time. ln some cases ready access to one of the buckles 14C may be prevented, in which event, the remaining buckle may be emplo ed.

(lbviously,

tails and in the arrangement and location of parts may be effected Without departing from the spirit andscope of my invention.

l claim as my invention: l 1. ln a vulcanizer, the. combination with variations in the structural deers longitudinally disposed in pairs on the respective sides thereof and spaced therefrom and a 'handle containing the heater leads, of a plurality of belts of pliable material severally coperating with said rollers in pairs for strapping said Working member in position.

In testimony whereof, I have hereunto subscribed my name this 3rd day of Jan.
